Structure and properties of a high-porosity glass ceramic containing biological hydroxyapatite

Descriptions are given of the production conditions, microstructure, and properties of a glass ceramics containing silicon, sodium, and boron oxides together with the ash from animal bones. Two-stage sintering has been used > 1300K and < 1100K. The bulk porosity is in the range 11-72%. Details...

Description
Summary:Descriptions are given of the production conditions, microstructure, and properties of a glass ceramics containing silicon, sodium, and boron oxides together with the ash from animal bones. Two-stage sintering has been used > 1300K and < 1100K. The bulk porosity is in the range 11-72%. Details are presented of the topical absorption in the range 0.2-25 mu m that are related to the presence of the biological hydroxyapatite. Such composites can be used as biomaterials.
